| Abstract: | The paper expounds on the mechanism of geotechnical fabrics and an analytical method of lateral displacement-settlement curves is proposed in the light of the measured data of an express highway,which has incorporated the concept of efficiency factor of load transmission.By using the analytical method,the effect of geotechnical fabrics in improving the bearing capacity of foundation,restricting lateral displacement and "squeeze-out"of soil,minimizing settlement of soil and enhancing the stability of soil against sliding has been analyzed. |
| Keywords: | geotechnical fabric efficiency factor of load transmission express highway soft soil improvement application |
